The trial is set for April for two men accused in a Bronx marijuana grow house explosion and fire that killed FDNY Battalion Chief Michael Fahy.

Fahy, 44, was a Rockland County native and 1990 graduate of North Rockland High School who lived with his wife and three young children in the Crestwood section of Yonkers. He was directing operations at the scene of a gas leak in the Kingsbridge section of the Bronx Sept. 27, 2016, before the building exploded and part of the roof struck him in the head and chest.

The trial for suspects Garivaldi Castillo and Julio Salcedo, who are accused of running the large marijuana grow house that caused the explosion, is scheduled to begin on April 10 in Bronx County Supreme Court.

Both were charged with manslaughter.

"My client is eager to have his day in court and vindicate himself against these charges,” Castillo's lawyer Daniel McGuinness said. "He’s been waiting a long time."

McGuinness filed a motion at the end of August to sever the cases of Salcedo and Castillo, but Judge Steven Barrett denied the motion.

He said in his ruling that Castillo's claim that a "joint trial would give rise to a situation in which there were potentially conflicted defenses between he and his co-defendant is denied as vague and speculative."

“It’s unfortunate,” McGuinness said of Barrett's ruling. “ They would have had a fair trial if they were tried separately.”

Approximately 20 other people were injured, including other firefighters and police officers.

Fahy was a 17-year member of the FDNY whose father, Thomas Fahy, had also served as a department chief. Michael Fahy earned degrees from Binghamton University and New York Law School before joining the FDNY in 1999.
